Solar Cells create A/C Current?

Question

I'm a little unsure about the type of current produced by photovoltaic cells. It appears that they create A/C current b/c we have the electrons in the n-type material filling the holes in the p-type material in which case holes are subsequently created in the n-type material and then electrons go back there to fill up the holes. So it seems like there's a continuous desire to be balanced. But this creates A/C current. Right? Do we put in diodes to rectifiy the current? I'm just a little confused here. thanks

Answer 1

No, DC only. If you need AC, an inverter is required. If your power needs are low, no problem but if you need a lot of power, this will be not very efficient. This system can be purchased from an RV supply. Many RV's have these installed at the factory.

Answer 2

AC not A/C.

AC is Alternating Current, and DC is Direct Current.

Alternating Current is seen in the wave form. Using 120 volts the voltage will start at Zero and go up to 120 volts and then go back down pass zero to 120 volts negative then back to zero again. Known as one cycle.

Direct Current is a flat line with no wave form. The only change in the wave would be from the start where the voltage is strong. If using 12 volts you have12 volts at the start and depending on your wire size and how long the wire is the other end might be 11.9 volts. But no wave form so it is not Alternating Current.

You are confused at what makes AC and DC voltage. The link below provides more information.

And yes you have to use diodes and/or rectifiers to change DC into AC.

Answer 3

Solar cells produce only DC. The electrons (and the holes, which is just a negative flow of electron vacancy) flow are filled up by more electrons being knocked off the atoms by the incoming photons, and the resupply of electrons coming back from the external circuit that make use of the DC power.

Answer 4

Photovoltaic cells produce current that flows in one direction, DC power, The current does not alternate to create AC.

Answer 5

For ur better information the Solar cell just transfers one form of energy to another form of energy i.e solar to electrical energy.And the the Solar energy is stored in the form of electrical energy in batteries in form on D.C.But it can be converted in AC by providing inverter and We can have AC current that what u want.Right so u got ur answer.

Answer 6

i trust that the flexibility cost of manufacturing photo voltaic cells has lengthy gone down significantly contained in the merely correct few years. that's, it now takes a lot less power to provide them than it did in years previous. it would want to be thrilling to the contact whomever made that actuality, and ask them for his or her documents. photo voltaic cells very last a lengthy time period, and now produce extra power consistent with sq. foot than ever earlier, so over that's lifetime, a photo voltaic cellular produces a heck of various power. food for concept although. strong question!

Answer 7

Solar cells act just like batteries ,meaning they produce DC current.
